i upgraded my dell inspirion N5050 from windows 7 x64 home to windows 7 x64 pro. since the upgrade on operating system my laptop can not read wifi from router. I tried to find a compatible wireless driver and even reinstalled the factory wireless drivers. And still it will not scan, find, or even pull up the connect to wireless network. I aalso have an issue with the network controller, it cant even upgrade, roll back or find a new driver. the old wireless driver was Dell wireless WLAN 1502 half mini card driver. can someone help
